I don't know, but you can bet that if it's from Nintendo it will be underpowered at best. They seem to be experts at churning out wimpy hardware and making it insanely popular.
I would love a handheld with the power of at least the Gamecube though.
I KNOW! How about they release the Nintendo Hardcore! It would have NO casual noob games whatsoever, no sickeningly sweet cutesy crap games, just all the best "manly" games on it. I'd buy that.....well, pirate the hell out of it anyway. LOL!
Of course, I bought a DS thinkin DS stood for Dead-Serious, but the joke was on me. It turned out to be a bottle of pancake syrup in electronic form.
